I have been lead to believe (from soe previous posts) that the iGesture pad uses one finger for cursor tracking (arrows). However, on the TouchStream LP, the left pad is used, and it takes two fingers (like mousing on the right side), hope that helps...

Actually, I use two fingers for arrows on the iGesture, but they don't work at all on the TouchStream. I've tried both left and right handed. Anyone else with a TouchStream use the arrow gestures? They're printed on the gesture cheat sheet that comes with the keyboard.
